Erroneously humbling himself before the Iga, Gennosuke is the very definition of honorable.In hopes of winning their admiration for the sake of his botrothed, Oboro, he will do anything to ensure their matrimony. While Gennosuke tries to break the long-lasting hateful tradition and welcome the Iga as family, they plot against him, picking off his clansmen one by one. Well loved by the Kouga, Gennosuke is feared greatly by his enemies. He is thought to be so powerful that the Iga avoid direct confrontation with him at all costs. This fear is greatly justified for he posseesses the ultimate doujutsu technique, taught by his master Hyoma.
